Introduction

This report is a graphical summary of the elevated-temperature strength data for chromium steels. It includes summary curves for tensile strength; 0.2 per cent offset yield strength; per cent elongation and reduction of area; stresses to produce rupture in 100, 1000, 10,000, and 100,000 hours; and stresses for creep rates of 0.0001 and 0.00001 per cent per hour (one per cent in 10,000 and 100,000 hours). Data for 23 steels ranging from 12 to 27 per cent chromium are given.
